How much does it cost to unclog a drain professionally?

Professional drain unclogging from Wisler Plumbing, Heating, Cooling & Electric is often $99 when using our advertised drain cleaning special that includes a free video inspection. Actual cost can vary by drain location, access, and whether a deeper sewer problem is discovered; we provide a fixed, upfront price before work begins and confirm final pricing after we assess the issue on site. Our licensed technicians handle these jobs throughout the Roanoke Valley, including the Cave Spring area. Same-day help is available for urgent sewer problems.

Price may change when any of the following are present:

• No accessible cleanout or hard-to-reach piping
• Main sewer line blockage versus a single fixture clog
• Heavy root intrusion, broken or collapsed pipe needing repair
• Add-on work such as trenchless repair, repiping, or sewer replacement

If drains overflow or multiple fixtures back up at once, avoid chemical cleaners and call a pro promptly. <br/> Updated: 2026-04-10 <br/> Need help in Cave Spring, VA? Call (540) 238-0320 or book online.
